Patent DE-3842795-A1 (DE)
Title: Solenoid injection valve for internal combustion engines
Inventor: SCHAUER WALTER
IPC: F02M51/06
Filed: 1988-12-20
Abstract: In known solenoid injection valves the spring force loading the valve element is adjusted by sometimes costly means of adjustment and setting operations. The new injection valve is characterised by the ease of the manual setting sequence for the spring loading the valve element. By means of a spring plate supported on the spring, on which plate a clamping sleeve is arranged, which is clamped axially displaceable in a recess of the valve upper part, the spring plate is pressed into a certain holding position prior to assembly of the valve and after assembly of the valve is pressed through the recess into its final position by means of a tool. Injection valves of this type have applications in fuel injection systems for the fuel feed of internal combustion engines.

Title: Flow or pressure regulating valve - has inbuilt by=pass port providing fail=safe function
Inventor: HERTELL SIEGFRIED DIPL ING
IPC: G05D16/10
Filed: 1990-08-11
Abstract: The regulating valve for use in hydraulic systems has a control spool (9) with a pair of control surfaces (10,17) that operate relative to ports (8,16) in the valve block.  The position of the spool is dependent upon the difference in force applied by fluid pressure at one end (20) and a spring at the other other. As the pressure in inlet fluid (3) rises the spool moves to reduce the outlet (8) and so regulates the  pressure. The other port (16) operates as a safety device in that very high pressure transients cause the valve to block  the normal output and the port acts as a bypass. ADVANTAGE - Provides fail safe facility.
